Abstract:

CH3I was photolyzed at 20 K in solid matrix materials, N2, Kr, and Xe, containing hydrocarbons C2H6 or CH33CH or deuterated hydrocarbons CD4, CH3CD3, or CH33CD. H abstraction was studied by infrared detection of CH4 and CH3D. In the solid, the abstraction products can be attributed to CH3 radicals with an effective te perature in the range 1000 - 3000 K. The products obtained from photolysis of CH3I with C2H6 present as well as those from photolysis of C2H5I in N, indicated that about 85 of the reactions probably occurred within the cage at the site f photon absorption. These studies provided information concerning the dissipation of the energy of a hot radical constrained within a reactive cage. Author
